Not sure based on the release notes when this happened, but somewhere between Build 8629
and Build 8930 the monthly default calendar view was changed. Each day now displays a maximum of 3 or sometimes just 2 events before having a grey + x more bar.

Before it used to display far more events, perhaps even all of them I don't recall exactly. Is there way this could be brought back, if not by default then via a user settings option. We have quite a few customers that miss this and feel 2-3 events is just too limited for a quick monthly overview, even if it means having to scroll a bit.
